Abstract
A atrial tracking cardiac stimulator for detecting atrial activations of a heart through an atrial lead associated with at least one of the atria of the heart and delivering ventricular pacing pulses to the heart through a ventricular lead associated with at least one of the ventricles of heart. The stimulator includes a pulse generator including an output stage which delivers a pacing pulse to the ventricular lead responsive to a conducted atrial activation. A sensor is coupled to the atrial lead for detecting atrial activations. A rejectory processor times rejectory time periods responsive to detected atrial activations. The refectory processor further provides a conducted atrial activation to the pulse generator when a detected atrial activation occurs outside of a rejectory time period.
